School sores (impetigo) - including symptoms, treatment and prevention

School sores (impetigo) are a superficial skin infection caused by Staphylococcus or Streptococcus bacteria, or sometimes both, that is most common in children.

4 to 10 days.

As long as there is discharge from the sores. School sores are extremely infectious.
